Preparing geometry : scanline / vray

[murko-sk]

Hi,
I`m doing recently some tests on our project, it is quite a large one( thousands of objects, a lot of hipoly instances, about ~23mil poly total ). The tests consist of comparing the time needed to prepare geometry ( the phase after it start`s `rendering`) in scanline & vray. It shows surprisingly that scanline is about ~10x faster ( 20-sec on scanline to 200sec on vray ) on the same result. No lights involved ( only default ), all objects have simple plain native material ( standard `grey` , vraytml `grey` ). I made some changes in raycaster settings according to vray manual, but it`s nowhere the speed of scanline. Did I miss something on such scenario ?\

V-Ray does some additional tracking of object dependencies to determine the correct order of evaluating objects, so it could be expected that it is somewhat slower. However to tell for certain where the slowdown comes from I will really have to look at the particular scene.

Best regards,

Hi,
thanks for reply, I`ll try to prepare scene for you.
